Background
Unicorn implemented in 1990 (no previous online LMS)
King’s Fund collects health and social care managementmanagement material – not clinical information
No suitable tool for subject indexing, not even DH-DSS Data
![Page 3: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/3.jpg)
Why not MeSH or LCSH?
Too clinical (MeSH)
Too broad-based (LCSH)
Management terms in both are under-
developed for our purposes
Both too American!
![Page 4: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/4.jpg)
What next?
Two senior librarians nominated to compile a health & social care management thesaurus
This can be used in-house and sold to income generate
Work takes about 2 years However,
the product is useless…the product is useless…

At last!
The DoH puts up money to update the
existing DH-DSS Data thesaurus
An experienced librarian is appointed
(Phil Defriez – lovely boy! )
KF staff assist Phil (remotely)
HMIC thesaurus is finallyfinally published in
2001
![Page 7: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/7.jpg)
How to get the thesaurus on
Unicorn? The original KF thesaurus had been keyed
into Unicorn by a temp – it took months!
No budget – KF didn’t have the money to
pay for it this time
Time factor – the project had been
running for years. It was high timehigh time the
thesaurus was implemented
![Page 8: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/8.jpg)
In the bath one day (honest!),I had a brilliant idea...
![Page 9: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/9.jpg)
My brilliant idea I had a Word file of the thesaurus (total
of 377 pages – 10784 + terms) If I could do a search and replace on the
relationship terms (BT/NT/RT) and turn them into MARC fields, we could load the file onto Unicorn!!
![Page 10: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/10.jpg)
Will it work?
I called Sirsi (of course!)(of course!)
Each individual authority record needs to be
formatted according to a template
If I can do this, the file can be saved in text format
This can be uploaded to our server
![Page 11: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/11.jpg)

This is going to be easy...
Now it’s just a simple matter of search and replace!
Did I say simplesimple?
![Page 13: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/13.jpg)
Not so easy...
The Word file has ditto marks where there are more than one BT/NT/RT in a record!!!
INFORMATION MANAGEMENT SYSTEMSBT Information systems
NT Cataloguing systems
.. Classification systems
.. Indexing systems
RT Information management
![Page 14: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/14.jpg)
Is this the end of my brilliant idea?
An agonised phone call to Phil:Would it be possible to give me a Word document of the file where each BT/NT/RT was repeated?
YESYES!!
Phew!
![Page 15: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/15.jpg)
Next problem...
In the printed thesaurus, all terms (proper and improper) are listed in the A-Z sequence
BUTIn the Unicorn authority module, only proper terms have their own entries
![Page 16: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/16.jpg)
Solution?
All the improper term entries have to be stripped out manually, e.g.
Mental handicapUSE Learning disabilities
![Page 17: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/17.jpg)
The next problem?
Pre-coordinated terms from the old thesaurus which had been post-coordinated in the new had to be stripped out manually, e.g.
Nurses roleUSE Nurses [AND] Professional roleFinding them was easy…
![Page 18: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/18.jpg)
Surely that’s it?
Unfortunately not! Many improper terms have the same words as the proper terms they refer to:
RESEARCH SAMPLINGUF Sampling in research .. Sampling [research]
![Page 19: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/19.jpg)
Now?!
Still not… Some improper terms have been used as part of proper terms:
Advisers [consultants] USE ConsultantsAdvisers [counsellors] USE Counsellors There is also a proper term
Medical advisers
![Page 20: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/20.jpg)
Almost there...
But not quite! Many terms contained the word “and” - this needed to be changed to & so the Boolean operator AND will work properly
![Page 21: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/21.jpg)
Caveat…
As long as you remember not to replace just the string ‘and’‘and’ alone OR
Manual handling becomes…
![Page 22: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/22.jpg)
At last!! The editing was finished The file was saved in text format and
emailed to Sirsi The old authority module was deleted The file was loaded onto our backup
server for testing…
Fingers crossed!Fingers crossed!
![Page 23: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/23.jpg)
First problem Some of the records had “collided” Only proper terms were coming up
in the BROWSE AUTHORITYBROWSE AUTHORITY listing - no sign of any improper terms…
A quick phone call to Barbara and a little tweaking of Format Manager and...

Well…??

Finally!
The text file was loaded onto our main server
The rebuild authority reports were run and…

However...
That’s not the end of the story.
The next issue is:
How to maintain the How to maintain the thesaurus?thesaurus?
![Page 27: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/27.jpg)
Thesaurus maintenance 1
We have a spreadsheet on a shared drive, accessible to all those indexing
We add new terms, disputed existing terms or terms that don’t work as we find them
This is sent to Phil (love ‘im) to decide which terms will be added and to establish the relationships (no hard work for us!)
![Page 28: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/28.jpg)
Thesaurus maintenance 2
We add any new terms to the authority module as PROVISIONAL terms
If possible, we retrospectively index any old records
The globaledit report has been working overtime at the King’s Fund!
![Page 29: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/29.jpg)
Thesaurus maintenance 3
Get the new terms Upgrade the PROVISIONAL terms to
AUTHORISED Edit the relationship terms Run the unauthlst report once a month Check all the unauthorised terms listed
![Page 30: Implementing a new thesaurus on the King’s Fund Unicorn system or Eureka! The best ideas happen in the bath… Liz James EUUG Conference, Paris 2002.](https://reader030.fdocuments.net/reader030/viewer/2022032701/56649c9d5503460f9495cb9f/html5/thumbnails/30.jpg)
The future? (Aaah, aargh and
phew)
The HMIC thesaurus is going to die (aaah)
We will be using the bigger DH Thesaurus at some point soon (aargh)
At least I know how to do it now (phew)
PIECE OF CAKE!PIECE OF CAKE!
